A synthetic peptide fragment of thymosin beta-4, researched for wound healing and tissue repair.
Myocardin-related transcription factors (MRTFs) are robust coactivators of serum response factor (SRF). MRTFs contain three copies of the RPEL motif at their N-terminus, and they bind to monomeric globular actin (G-actin). Previous studies illustrate…
Thymosin beta 4 (Tβ4) and thymosin beta 10 (Tβ10) are two members of the β-thymosin family, involved in multiple cellular activities in different organs in multiple animal species. Here we report the expression pattern of Tβ4 and Tβ10 in rat tissues,…
Thymosin β4 (Tβ4) is an actin-binding peptide involved in tissue regeneration and angiogenesis. This 43-amino acid peptide is chemically synthesized for research or clinical trials. To overcome the high costs of solid phase synthesis, we developed a…
Thymosin β4 (Tβ4) is one of the most promising thymosins for future clinical applications, and it is anticipated that commercial demand for Tβ4 will increase. In order to develop a new approach to produce recombinant Tβ4, a 168 bp DNA (termed Tβ4) wa…
Thymosin beta4 (Tβ4) has multi-functional roles in angiogenesis and arteriogenesis, but little is known about its mechanism. The Notch signaling pathway is important in regulation of angiogenic behavior of endothelial cells, in addition to vascular e…
OBJECTIVE: Despite major advances in its diagnosis and treatment, gastric cancer (GC) remains a major life-threatening disease. Treatment of the disease is further aggravated by the lack of diagnostic biomarkers that can aid in the early detection of…
BACKGROUND: Actin-based cell motility is fundamental for development, function, and malignant events in eukaryotic organisms. During neural development, axonal growth cones depend on rapid assembly and disassembly of actin filaments (F-actin) for the…
Previously, we found thymosin β4 (Tβ4) is upregulated in glomerulosclerosis and required for angiotensin II-induced expression of plasminogen activator inhibitor-1 (PAI-1) in glomerular endothelial cells. Tβ4 has beneficial effects in dermal and corn…
Mesenchymal stem cells (MSCs) hold great promise for the field of tissue regeneration. Because only a limited number of MSCs can be obtained from each donor site, it is important to establish standard methods for MSC expansion using growth and trophi…
Thymosin β4 (Tβ4) is a small peptide composed of 43 amino acids. It has many important biological functions, such as promoting cardiac repair and wound healing, and therefore has great potential in clinical applications. In this report, we describe a…
We recently reported that overexpression of thymosin beta-4 (Tβ4) in transgenic mice promotes abnormal hair growth and tooth development, but the role of Tβ4 in dental pulp regeneration was not completely understood. The aim of this study was to inve…
Thymosin proteins are well known for their actin-binding activity. Thymosin beta 4 (Tβ4) has been associated with biological activities in tissue repair and cell migration via interaction with ATP-synthase in vertebrates, while the information of sim…
The role played by thymosin β4 (Tβ4) in the process of wound healing was reported in several organs. However, there have been no reports that investigated the role of Tβ4 in the repair process after ligament injury. The purpose of this study was to d…
PURPOSE: This study aimed to evaluate the effects of thymosin β4 (TB4) on bone formation. METHODS: A 5mm diameter bone defect was created in the skulls of Wistar rats. Two types of experimental models were prepared: one with atelocollagen sponges use…
OBJECTIVE: To investigate the efficacy of leukemia inhibitory factor (LIF) and/or glycoprotein 130 (gp130) on in vitro growth of human embryos. DESIGN: Laboratory study. SETTING: University hospital-based IVF clinic. PATIENT(S): A total of 164 frozen…
RATIONALE: Rossdeutsch et al describe a requirement for thymosin β4 (Tβ4) in vascular development. Impaired mural cell migration, differentiation, partial embryonic lethality, and hemorrhaging were observed after analysis of 2 lines of mice, one of w…
Nanog, Sox2, and Oct4 are key transcription factors critical for the pluripotency and self-renewal of embryonic stem (ES) cells. Their downregulations lead to differentiation, accompanied with changes in cell motility. Whether these factors impact ce…
β-thymosins, including thymosin β4 (Tβ4), Tβ10, and Tβ15, are a family of highly conserved 5 kDa peptides. They are involved not only in normal cell migration, but also in tumor metastasis. However, the molecular mechanisms of β-thymosins to regulate…
